Berichtigung: How Big is the Pinacol Boronic Ester as a Substituent?

The 74:26 ratio observed for cyclohexyl pinacol boronic ester 4 corresponds to an A-value of 0.38 kcal mol−1 and not 0.42 kcal mol−1, as incorrectly reported in Scheme 2 and in the main text of this Communication. An A value of 0.42 corresponds to a ratio of 76:24. This correction does not alter the content of the paper.
